Abstract

Precision studies of Drell-Yan production of high-transverse momentum leptons at hadron colliders require that electroweak and QCD higher-order contributions are simultaneously taken into account in theoretical predictions and data analysis. A detailed phenomenological study of the impact of electroweak and strong contributions, as well as of their combination, to the most important observables relevant for single W and Z physics programme at hadron colliders is presented.

Abstract

Abstract: We have implemented a code for jets production in ALPGEN, with decays into several final states, including and . The MLM prescription is used for matching the matrix element with the parton shower, including in this way the leading soft and collinear corrections. In order to demonstrate its capabilities, we perform a combined analysis of and production for a heavy leptophobic gauge boson. It is found that the effect of the extra jet cannot only be accounted for by a K factor multiplying the leading-order cross section. In fact, the combined analysis for and presented improves the statistical significance of the signal by 25% (8.55σ versus 6.77σ for a mass of 1 TeV), compared with the results of an inclusive analysis carried out on the same sample of events.
